Pipe rust prevention, the BBC in the UK has introduced NMR pipe protectors.

Preventing red rust in the air conditioning pipes of the BBC and extending the lifespan of the pipes by preventing leaks with the red rust prevention device "NMR Pipe Protector."

The air conditioning piping in the BBC's main block building is 53 years old and has been experiencing leaks due to red rust deterioration. To avoid disruptions in program production during the pipe renewal work, a red rust prevention device called the "NMR Pipe Protector" was installed. The effectiveness of the NMR Pipe Protector in preventing red rust was verified in just about a month. Before installation, the iron content in the circulating water of the cooling water piping in the main block building was very high at 5.53 mg/L, indicating serious red rust deterioration. However, a water quality test conducted 32 days after the installation of the NMR Pipe Protector showed a significant reduction to 0.05 mg/L, which is less than 1/100 of the previous value, demonstrating the rust prevention effect due to the black rust formation caused by the NMR Pipe Protector. In the Stage 5 building, the iron content was also very high at 3.80 mg/L before the installation of the NMR Pipe Protector, but after installation, it decreased to about 0.06 mg/L, which is approximately 1/63 of the previous value, completely preventing red rust deterioration in the cooling water piping. Even in the 53-year-old BBC building, the high effectiveness of red rust prevention has been proven to prevent leaks and extend the life of the piping. *For more details, please refer to the PDF document or feel free to contact us.*
